Definitions

  • the invention is about a dental suction arrangement which removes saliva and other fluids from a person's oral cavity.
  • the suction arrangement includes a suction tube and an absorption body to be placed in the oral cavity, thereby the suction tube includes a suction part which is arranged in the absorption body and which is equipped with a hole member communicating with the absorption body.
  • the removal of saliva and water is mainly performed using two kinds of suction devices including tubes with different dimensions, where the thicker one is a so called high-speed suction device that efficiently removes large volumes of water and saliva, and which is operated manually by the operator or his assistant.
  • the suction device with a thinner dimension and lower suction capacity is mainly used in connection with a device which is fixed in the oral cavity and where the removal of saliva and water works automatically without impact of the operator. Often the suction device also works as a protection of the tongue against rotating instruments by keeping away the tongue.
  • a thinner dimensioned suction device is described in US 3,086,289 .
  • suction arrangements consist solely of various kinds of plastic tubes, straight or pre-bent in different shapes, with holes placed in one end or along the tube.
  • GB 1 060 288 A relates to a surgical sponge stick comprising a tubular handle of resilient plastics material having a partially flattened portion with perforations through its wall at one end and porous absorbent material forming a surgical sponge mounted on the partially flattened portion covering the perforations.
  • US 2013/203012 A1 relates to a siphoning device suited for automatically removing fluid/ blood from a surgical site, having a length of sterile flexible tubing that is configured into a loop, the tubing having a first open end, a second open end, and a central portion. At least one or more sets of a plurality of holes punctuating a circumference of the central portion of the loop are provided, which are distributed along a longitudinal direction of the tubing, and sterile absorbent covering encompassing the one or more sets of the plurality of holes, the covering being permeable to bodily fluids.
  • One object of the present invention is to remove the problems associated with the prior known technic in the field and thus provide a more effective absorption of saliva and other fluids than previously offered.
  • the suction arrangement is made of elastically deformable material in order to adapt to the anatomical shape of the bottom of the mouth.
  • the main part of the outer surface of the suction arrangement will be connected with areas at the bottom of the mouth from where the fluid will be absorbed. This enables a more effectively and completely absorption.
  • the suction line with the absorption body extends not only to the lower part of the lower jaw but that it extends along the lower part of the lower jaw.
  • the absorption body is sort of clamped between the tongue and the lower jaw, such that it will not unintentionally disengage from this place.
  • the suction arrangement which comprises elastically deformable material, adapts to the bottom of the mouth and covers the area without causing any discomfort for the patient and at the same time preventing the saliva to come in contact with the teeth, and further the device is retained at the bottom of, the mouth since it is partially placed under the tongue.
  • the suction line may be deformed as desired to be adapted to the best position. It may extend over the molars or incisors to then extend close to and along the lower jaw in the distal direction. Preferably, it reaches the lower part of the lower jaw, i.e. a level level below main tongue extension close to the canine, and then extends under tongue along the premolars and molars.
  • the suction line is preferably made of plastic material which is easy and plastically deformable.
  • the absorption body may be fixed the suction part of the suction line in any suitable manner, such as by glueing or by friction.
  • the suction arrangement is suitable both for to be applied to the left or the right lower jaw.
  • the absorption body within the suction arrangement also works as a pump when it is compressed due the movement when the patient swallows and the subsequently expansion.
  • the elastic absorption body In order to ensure the desired and beneficial pump action, it it essential for the elastic absorption body to have a compressibility to half of its original volume by standard tongue force.
  • the compressibility may be considerable higher, i.e. up to 85 percent.
  • the material of the absorption body may be soft open foam with a low elasticity coefficient, or a soft flocking, or a silky mesh covering the inner absorption body.
  • the absorption body also eliminates the need to interrupt e.g. the ongoing dental cleaning treatment for adjustment of the suction device when it causes painful pressure to the patient's inside of the lower jaw which is very pain sensitive.
  • the suction arrangement adapts itself to the anatomical shape of the bottom of the mouth and also is elastic, it automatically very efficiently adapts to the exact anatomical shape in a way which is not possible with a simple cylindrical absorption body under known technique. Also the dental treatment will be more silent since absorption body acts as noise shield, dampening the suction noise emitted by suction holes.
  • the created anatomical form effectively allow the reception of saliva leaving both Glandula Sublingualis and Glandula Submandubularis, and the device builds a barrier between the teeth and the saliva glands.
  • the absorption body shows, in a cross sectional view, perpendicular to the length extension of the absorption body, a non-circular contour.
  • the absorption body shows, in a in a cross sectional view perpendicular to the absorption body's length extension, a contour with a base and a top, where the mentioned base is broader than the mentioned top. This shape facilitates the placement and retention under a part of the tongue.
  • the absorption body has a part, which, in a cross sectional view perpendicular to the absorption body's length extension, shows a contour with at least one concave part. With the concave contour part the shape of the absorption body is adapted in a natural way in order to create space for the tongue. This will avoid concentration of pressure at the tongue and at the same time the absorption body effectively reaches areas, over as well as under the tongue, where the absorption is most needed.
  • the cross section of the absorption body is larger below the area of the waist which is created by the tongue and slightly smaller above this waist.
  • the suction part of the suction tube' is preferably arranged at the lower, broader part.
  • the suction tube is made of elastically deformable and adjustable material in order to obtain an adaption to the anatomical shape of the bottom of the mouth and placement position. This embodiment includes a variety of application possibilities.
  • the suction device and its related suction tube or suction line and absorption body especially can adapt itself to different sizes of the bottom of the mouth, but also since the absorption body is so long it has the possibility to extend along the alveolar area or gingival area of the jaw at the incisors and canines as well as at premolars and molars, and due to the cross sectional shape it adapts to the different parts.
  • the suction device includes an extension part which, when placed in the oral cavity, extends backwards towards the throat, whereby the extension part preferably has a reduced cross-sectional area which decreases in the direction of the throat.
  • the extension part reaches a bit down in the throat which helps reducing the accumulation of fluid in the throat, which otherwise may cause discomfort and disturb the dental treatment due to swallowing reflexes.
  • the extension part generally entails a lower fluid level.
  • the absorption body is adjustable in its length.
  • a long absorption body will be prefabricated, and it will be shortened but cutting it.
  • the absorption body may be fixed by friction on the suction part of the suction line, and be manually extended and shifted according to the needs.
  • the suction part may be provided with a punch pattern, allowing its extension together with the absorption body.
  • the hole member comprises multiple holes. This facilitates the transport of fluid from the outer surface of the absorption body to the absorption part or suction part since the transport routes become shorter.
  • the multiple holes are distributed along the absorption part as well at its circumference.
  • the holes are of different size and/or shape.
  • the hole size and/or shape or both can thus be adjusted to local variations in relation to the need of absorption at the different points of the absorption body.
  • the need of absorption may vary depending on where the saliva is produced, on locations where saliva tends to accumulate, on locations where other fluids accumulate and on variations in the absorption body's deformation. Also from a flow technical point of view it is favorable to be able to have different sized holes depending on their distance to the connection of the absorptions part to the rest of the suction device.
  • the suction device includes a secondary absorption body to be placed at the Glandula Parotis excretory duct, where the secondary absorption body is in fluid connection with the absorption body.
  • a substantial part of saliva is produced by the Glandula Parotis excretory duct, i.e. a salivary gland located in the back upper cheek area.
  • a salivary gland located in the back upper cheek area.
  • the secondary absorption body and the absorption body are connected with each other via a connecting line which can be called secondary suction line. It would also be possible to achieve the transport by capillary action through an extension of the absorption body to the secondary absorption body. However, the flow becomes more efficient in case if performed through a line between the both bodies.
  • the suction device includes multiple absorption bodies and the suction tube includes additional lines, whereby each additional line is connected with a suction part in the respective absorption body.
  • the secondary suction line may be formed such that a spring force is exerted between secondary absorption body and the primary absorption body. By this, both are kept in place, and the primary absorption body is pushed down to be closer to Glandula Lingualis.
  • This embodiment allows for a simultaneously fluid removal from several locations in the oral cavity with just one suction device.
  • the user can decide freely whether absorption bodies should be placed on two or several different points on the right side between the tongue and the row of teeth, on the right side between the row of teeth and cheek, correspondingly on the left side, between the row of teeth and lip, at the Glandula Parotis or on other points in the oral cavity.
  • the respective suction part is detachably connected with the rest of the suction line.
  • the suction device includes a suction line and a set of multiple absorption bodies in different embodiments in respect of the anatomical shape and/or size.
  • the suction device includes a protection shield which may be a tongue protection in order to block the tongue.
  • the tongue protection aims to protect the tongue from rotating instruments during the dental treatment such as cleaning treatment, and also to prevent the tongue from touching the tooth or teeth in critical areas which may cause a contamination with saliva when performing different filling and/or cementation of prosthetic constructions.
  • the tongue protection is arranged at an extension of the suction line, and in another embodiment, the tongue protection is arranged at one sidearm of the mentioned suction line.
  • the tongue protection is made of a material which is elastically deformable.
  • the tongue protection is made of a material which can be broken off in order to adjust the fitting and placement in the oral cavity and also in order to enable an increased access and insight, while the ability to protect the tongue is retained.
  • the tongue protection is arranged adjustably to the suction tube. This is an additional opportunity to perform specific adjustments depending on the condition of the patient.
  • the tongue protection has an absorption capacity.
  • This absorption capacity can either be provided in case the tongue protection is made of absorbable material, or covered any absorption material or in case the tongue protection is equipped with a - secondary - suction line which is connected with the suction device and its absorption body.
  • the respective tongue protection and suction part are detachable connected with the rest of the suction tube.
  • the secondary suction line between the tongue protection and the absorption body may be such that it is bias to separate the tongue from the lower part of the lower jaw. By this, the absorption body is pressed downward towards the Glandulae under the tongue.
  • the secondary suction line advantageously is bent by about a little less than 180 degree.
  • the tongue holder may be provided with a grip, like a small lateral extension.
  • a grip like a small lateral extension.
  • the tongue holder is turnable and/or attached via a plastic hinge to the secondary suction line.

  • a silky mesh such as known from jewelry boxes.
  • Such a web or mesh has a surface with a low friction coefficient such such the absorption body may be inserted easily to its desired place. It has a very pleasant and comfortable feeling for the patient. Yet its permeability is sufficient to have the desired suction force retained therethrough.
  • the silky mesh is very thin and thus very flexible.
  • the absorption body is soft and flexible and has an elastic character. If it is made from foam or any other suitable material, a hardness gradient may be used such that it is harder close to the suction part and softer close to its outer periphery.
  • Such a hardness gradient automatically is provided if the absorption body is made of a flocking. Any desired shape and distribution is possible. Flocking has a very good capillary effect.
  • the suction arrangement is provided with a moisture sensor, intended to give a feedback to the vacuum pump and to reduce the pump action if the area under the tongue is dry. This will also reduce the vacuum pump noise.
  • the inventive suction arrangement is also very suitable for unteethed patients. Because of the spring action both to the absorption body between the tongue and the bottom of the mouth, and of the suction line between the chin and the lower part of the lower jaw, the invention works great independently of whether the jaws are fully teethed, partially teethed or unteethed.
